2 Claims.

This invention relates to a grenade and a gun for the shooting thereof, and has for the primary y vision of agrenade approximately the size of a hand type grenade sothat a large number of such grenades" may be handled and carried by a person and the gun is of such construction that the person may conveniently operate said gun froml the shoulder without disadvantages of any kind and has provision for permitting the ring mechanism of the grenade to be released .atany time'desired after the placing thereof in the gun, so that after thev release of the firing mechanism has taken place, the person may aim the gun at a selected target and lire the propelling charge ofk they grenade through the operation ofthe gun aswould be usual with any type of gun used from the shoulder. Further, the gun is oi` a construction to permit the grenadeto be easily placeditherein and to eject the shell of the .grenade after-a firing operation and also permit the gun to be taken apart for cleaning,v conl veulent handling, carrying and storing.

, With these and other objects in viewvas will become more apparent as the description proceesls, the invention consists in certain novel features of construction, combinationfandf;"arf

rangement of,Y parts which will be hereinafter .more fully` described-and claimed.

' For a complete understanding of my ventina, reference is to be had to the following lie's'crip-v tien and accompanying drawings, in which Figure 1 is a vside elevati'on, partly in section,'

illustrating a gun and the grenade therein, and

showing in dotted lines the barrel positioned for ,45 sig-ht. Thev front gun sight is indicated by the loading and unloading. v y

Figure 2 is afragmentary side elevation illustrating the barrel of the gun and a portion of the breech block as well as the slide for giving entrance to the barrel of the gun through the operation of the firing mechanism of the grenade.

Figure 3 is a transverse sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a vertical sectional view illustrating the grenade andshowing in detail the shell andr propelling charge for the grenade.

Figure 5 is arperspectlve view ofthe shell prior to its application Yto the grenade.,

Referring in detail to the drawings, the numeral 5 indicates as an entirety a gun especially constructed for the firing of` a'grenade 6, similar in construction to the hand-thrown type of grenade commonly used in Warfare with the addition of a shell 1 containing a detonator 8 and a propelling charge 9. The casing of the grenade is slightly modied from the casing now employed 'by the hand-thrown grenade by being provided with a smooth portion I0 for contact with theriflings Il of the barrel i2 of the gun. The grenade casing has a series of grooves to l5 define portionsf- |3 acting as shrapnel when the grenade bursts under the explosion of the charge contained within the casing thereof. Also, the grenade 6 includes the conventional timed iiring mechanism (not shown) and equipped with the safety pin 'le which must be` removed in order e to set the timed iiring mechanism in operation. The shell 1 is equipped `with a wedding I5 separating the propelling charge from the casing of the grenade, and also located in the shell is a'packing I6 arranged between the walls of the shell, wadding I5 and the casing of thevgrenade.

The grenade is releasably held inthe shell 1,

breach block i8 as well as aconventional ,type

of trigger-operated rlng mechanism i9.' "The ...barrel l2`o`f thelgun is mounted-on the breech fblock in `a conventional manner so thatv thef" barrel may-be swung relative tothe breech block owfgr' loading and unloading..vthereof. -The barrel adjacent'to the breech is provided with a hand opening I9 normally closed by a slide 20 equipped with a finger piece 2l for the operationol:said4 slide end whi'ciasis-"shapedto 'form arear* gun character 2,2 locatedon the barrel adjacent the muzzle thereof. The purpose'of the hand opening I9 is to permit the operator of the gun to easily reach the releasing pin I4 of the grenade,

after the placing .ofthe latter within the barrel.

The 'slide 20 'includes flanges 23 slidably fitted within grooves provided in the barrel so that the operator of the gun may readily move the slide to either cover or uncover the hand opening I9.

Any type of ejector, operated by the movement of the barrel 20 relative to the breech block, may be employed for ejecting the shell 1 after the grenade has been red by the gun. The barrel of the gun is of a length shorter than the average type of gun fired from the shoulder. However. the length of the barrel is sunlcient to assure the flight of the grenade in4 al straight course to a given target. 'Ihe shortness of the barrel has a distinct advantage of permitting the gun to be easily handled and aimed at a target and also to render the carrying of the gun comparatively easy.

A grenade of the character described and red from the gun especially constructed therefor will permit a person .to be more. accurate and destructive against an enemy than could possibly be obtained through the use of a hand-thrown type of grenade. Also a .person is free to assume a less hazardous position than when using the handthrown type of grenade. Further, the gun being especially constructed and designed for shooting a grenade eliminates the use of gun attachments which are now frequently adapted to army rifles for the shooting of grenades and is believed will be more practical and accurate in the hitting of a target with the grenade.

While I have shown and described the preferred embodiment ofmy invention, it will be understood fil that minor changes in construction, combination" and. arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

1. In a gun, a riiled barrel, a breech block movably connected to the barrel to permit movement of the barrel relative thereto for the loading of the barrel with a grenade having a safety release for the control of the .timed ring mechanism thereof, a shoulder stock on the breech block, said barrel having a hand opening in a wall thereof for the manual removal of the safety release, and means for opening and closing the hand opening.

2. In a gun, a riiled barrel, abreech block pivot- 'ally connected to the barrel to permit movement of the barrel relative thereto for the' loading of the barrel with a grenade having a safety release for the control of the timed firing mechanism thereof, a shoulder stock on `the block, said barrel i having a hand opening in a-wall'thereof adjacent the breech block to permit manual removal of the safety release, and a closure plate slidable on the barrel for opening and closing the hand opening and including an offset vto provide a i'lnger piece.
